Answer:
30cm2
Step-by-step explanation:
first find area of triangle
A = 1/2 *b*h
A = 1/2 * 9 * (4 + 3 +1)
I got the 3 from the other side of the cut out rectangle.
1/2 * 9 * 8 = 36
next find area of cut out rectangle
A = l * w
A = 3 * 2 = 6
Last, subtract area of triangle - area of cut out rectangle
36-6 = 30cm 2
Hello,
As h(x) is a bijection,
range(h(x))=dom(h^(-1)(x))={0,1,2,3}
Answer C
<span>A. Use the distributive property to write an equivalent expression for the rectangle's area. </span>
It's 4 because it is on the exterior.
